Why I choose plums for the crostata…

Plums are very nutritious low-kilojoule food. One medium-size fresh plum contains only 120 kilojoules and is a good source of such dietary fibres as cellulose and pectin. It also supplies useful amounts of several nutrients, including 6 mg of vitamin C and 150 mg of potassium.

In their dried form some plums become prunes, which are a more concentrated source of kilojoules and nutrients.
Plums contain anthocyanins, the reddish blue pigments that lend them their intense colour. These anti-oxidant pigments may help protect against cancer and heart disease by mopping up free radicals, unstable molecules that damage cells.
